PAPER-FOLDING MACHINE.

Specification of Letters Patent.

Patented Aug. 29, 191 5.

Application filed January 23, 1913; Serial No. 743,796.

To all whom it may concern:

Be it known that I, FREDERICK C. JULYAN, a citizen of the United States,and a resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and useful Improvement in Paper-Folding Machines, ofwhich the following is a specification, the principle of the inventionbeing herein explained and the best mode in which I have contemplatedapplying that principle, so as to distinguish it from other inventions.

The subject of the present invention is a machine adapted for foldingpaper, for oflice use in folding up ready for mailing a number of sheetsof equal size which must be picked up and folded singly. Machines foraccomplishing this end are already known, but difficulty has been metwith in these machines in that they are complicated in operation andconstruction, and hence are notcapable of continuously perfectoperation. Furthermore, some of these machines are open to the objectionthat they do not pick up and fold single sheets, but in many cases foldup together two, or possibly more, sheets, in which case the foldedsheets must be carefully looked over and those which are folded togethermust be separated.

' It is the object of the present invention to provide a machine whichis simple and compact in construction and is capable of continuouslyperfect operation.

To the accomplishment of the foregoing and related. ends said invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawings: Figure 1 is an end elevation of the machine;Fig. 2 is a side elevation showing the folding mechanism in its initialposition; Fig. 3 is a similar side elevation, but showing a part only ofthe machine and showing the folding mechanism in its operating position;Fig. 4: is a similar side elevation partially in section showing thefolding mechanism in its raised position; Fig. 5 is a similar viewshowing the folding mechanism in the position assumed after the foldingoperation proper has been completed; Fig. 8 is an elevation of theopposite side of the machine to that shown in Figs. 2 to 5 inclusive;and Figs. 6 and 7 are vertical sections showing details of construction,and are taken on the lines 66 and 7 -7 respectively in Fig. 1.

The operating mechanism may be mounted upon any suitable base or frame,the one here shown consisting of two vertically parallel sides 1 whichare spaced from each other and are connected by cross bars or rods 2.Each side member 1 of the frame is roughly triangular in form, thusproviding two upwardly extending portions which are adapted to supportcertain of the operating mechanism which will be subsequently describedin detail. The general features of the construction of the base are notof prime importance excepting so far as they cooperate with theoperating mechanism, such cooperating parts being described inconnection with the operating mechanism at the proper points in thedescription.

A suitable magazine for receiving a plurality of loose sheets isprovided, such magazine consisting of an open tray having a roughlyrectangular bottom l and upwardly extending arms 5, the magazine beingremovably and pivotally attached at one end to a rod 3 which is mountedhorizontally and transversely in the frame. This rod 3 may be removedfrom the frame, thus permitting the removal of the magazine which, whilenot an important point, yet increases the efliciency of the machinesince it permits the removal of an empty magazine and the substitutionof a previously prepared and filled one. That end of the machine whichis shown at the right in Fig. 2 will, for convenience of description, behenceforth referred to as the forward end, and such mechanism as extendsfrom end to end of the frame, such as the magazine, will have its endssimilarly designated. The rear end, then, of the magazine rests upon asupporting cam 6 which is attached to a shaft 7 suitably mounted in theside members 1 of the base and extending therethrough, a ratchet wheel 8being attached to the shaft exteriorly of the base, such ratchet wheelan operating direction, the function of the smaller pawl being rather torotate'the ratchet wheel upon actuation of the larger pawl than torestrain the same from rotation, although such is the effect of itsengagement with the wheel. A spring 65 is provided for returning thepawl 10 to normal position. The advantage of the adjustable support forthe rear end of the magazine is that as the paper held in themagazine-is folded up the surface of the pile of loose sheets will belowered, and unless it were made possible to raise this surface by somesuch means as the cam adjustment of I be rendered inefficient.

Intermediate the ends of the magazine I provide means for causing aslight bulge in the pile of loose sheets held in the magazine. Suchmeans comprise a plate 13 provided with two downwardly extending ears 11 loosely entering apertures in the bottom of the magazine, the otherside or edge of the plate resting upon screws 15 adjustably mounted inthe bottom of the magazine and extending above the surface of the same.Adjustment of such screws will position such other edge of the plate atvarious heights above the bottom of the magazine, thus causing the bulgein the paper which is desired at some point, the exact point beingdetermined by the operation of the folding mechanism, as will be betterunderstood after the description of such mechanism.

The folding mechanism is borne partially by a carriage which is movablysupported on the base. Furthermore, the folding mechanism is eitheroperated directly from the carriage or indirectly from the same throughsuitable shaftings and gears. Such carriage, then, consists of an openrectangular frame consisting of side bars 16 disposed externally of thesides of the base and connected by cross bars 17. The forward end of thecarriage is pivotally connected to two connected supporting members 18which are pivotally attached to the sides 1 of the frame. It will benoticed that both the magazine and the carriage are supported at theirforward ends about parallel transverse axes which are adjacent to oneanother. Attention is called to this feature as it is an importantadvantage in the operation of the magazine, as will be brought out inthe following paragraphs.

Means for adjusting the pressure of the rear end of the carriage uponthe surface of the pile of paper in the magazine are provided, suchadjusting means preferably consisting of a threaded rod 19 extendingrearwardly from the rear end of the carriage and bearing, adjustablymounted thereon, a weight 20. The purpose of such adjustable weight isto adapt the pressure of the rear end of the carriage which rests on thepaper to the quality of the paper which is to be folded, as it will beunderstood that the coarser and stiffer the paper the greater will bethe pressure which will be required to properly pick up and fold thesame.

Rotatably mounted in the rear end of the carriage is a friction roller21 which is provided with a gear 22 normally restrained from rotation,except in one direction, by means of a spring latch 23. A second roller24 is provided with extending axles 25 which are slidably mounted inparallel upwardly extending slots 26 formed in the sides of the frame. Agear 27 is disposed upon the roller 24 and is adapted to engage the gear22 on the friction roller 21 upon movement of such last named rollerinto substantial contact with the second roller 24. A guide in the formof a wire 28 is attached to the rear end of the carriage and extendsforwardly of the friction roller 21, the main portion of the wire lyingabove and between the two rollers. The purpose of such guide is toprevent the second roller 21 from impeding the raising of the paperafter the same is once folded. Disposed parallel with such slots 26 is arack 29 normally engaged by the gear 27 on the roller 21 The slots 26and the rack 29 form portions of circles having for their center theaxis of the carriage when the latter is moved into its limiting forwardposition, (see Fig.

The paper folding means which have just been described, and whichconsist briefly of the two rollers, are adapted to raise and fold asingle paper and to convey the same to receiving means which may be ofany suitable form, but are here shown as consisting of a plurality ofrollers 30, 31 and 32, the roller 31 being preferably a friction roller.Such rollers are mounted upon suitable shafts which are journaled in thesides of the frame, the rollers being parallel to the lower rollers 24and 21. The paper upon being raised is received between the rollers 30and 31, the friction roller 31 being operated to draw the paper upbetween such rollers into a pocket or envelop 33. The roller 32 takes nopart in such operation but is designed to cooperate with the roller 31in removing the paper from the envelop and again folding the same. Theaction of these rollers in again folding the paper and removing it fromthe envelop will be described at length hereinafter, and it is onlynecessary to say at this point that the paper will be removed from thepocket between the rollers 31 and 32 onto the stacking mechanism whichcon sists of two guides 34 suitably mounted upon the frame, anadjustable back 35 slidably mounted upon such guides, and an oscillatingshaft 36 oscillatorily mounted in the frame and provided with extendingfingers 37 which are adapted to receive the folded paper and to forcethe same against the back 35 or against the pile of papers already heldagainst such back. Attached to the shaft 36 is a link 38 which isslidably and pivotally attached to a pivotally mounted bar 39, suchsliding and pivotal attachment being by means of a lug 40 attached tothe link and held in an open slot 41 in the end of such bar 39. Theother end of the bar is adapted to be contacted by the side of thecarriage upon the operation of the latter, thus oscillating the bar andmoving the fingers as has been described. A spring 42 is provided forreturning the link and bar to their normal positions.

The carriage is adapted to be reciprocated longitudinally across themagazine moving from the position shown in Fig. 2, first forwardly andthen returning to its initial position. Resilient means in the form of acoiled spring as attached to a cross bar 2 of the base and to theforward end of the carriage are provided for moving the carriageforwardly. Mounted upon a bracket 66 attached to one side of the frameis a gear 44 to which there is adjustably attached a cam 4.5 in contactwithand operating a contact member 46 having a vertical contact face,and being mounted to slide horizontally upon a pm 47 mounted in suchbracket. The gear 44: is rotatably mounted' upon this pin 47. Suchcontact member is attached by means of a rod 48 to the forward end ofthe carriage, and it will be seen that rotation of such cam will limitthe action of the spring in moving the carriage forwardly and will alsopositively return the carriage to its initial position. Adjustment ofsuch cam will increase or decrease, as desired, the length of stroke ofthe carriage and will also determine the forward position to which thecarriage can be moved by means of the spring. Attached to the other sideof the gear 4A? is a second cam 49 which is adapted to engage the underside of the sides 16 of the carriage and to lift the rear end of thecarriage, thus tilting the same about its axis. It will be understoodthat the gear 4:4: is in reality a stub shaft for operating the twocams, and such shaft may be substituted for the gear if it is desired toposition the latter at some other point. The

relation between the two cams will be such that the lifting cam will notoperate to tilt the carriage until the reciprocating cam has permittedthe spring to move the carriage to such a position that the frictionroller and the second roller 24 are in substantial contact with thefolded sheet between, the gears 22 and 27 on such rollers being at thistime in mesh with one another.

Pivotally mounted in the sides of the base is a shaft 50 which extendsthrough one side of the base and is provided with a hand wheel 51 forconvenient rotation. Such shaft bears a gear 52 which meshes with anddrives the gear 44 which operates the two cams. The friction roller 31in the upper portion of the frame is also provided with an extendingportion which bears a gear 53 driven by such gear 52 on shaft 50. Theshafts 30 and 32 bear gears 5% and 55 respectively, each of which mesheswith a second gear 67 on the friction roller 31, such rollers 30 and 32being operated there fore from the friction roller 31. Mounted laterallyupon the rear end of the carriage is a lug 68 which is adapted to engageand operate the pawl 10 which rotates the adjusting cam for the magazineand raises the same. So long as the paper in the magazine is at apredetermined level, which is when it permits the folding mechanism toproperly operate, the lug 68 will not engage the pawl 10. Upon thefolding of a number of the sheets the surface of the pile will belowered and the lug 68 will then engage the pawl 10 and operate'themechanism upon each movement of the carriage until the rear end of themagazine has been raised to such a point that the folding mechanism mayoperate properly, at which point the rear end of the carriage will beabove the pawl 10, and further adjustment of the magazine will cease.

The operation of the mechanism will be as follows: In the initialposition of the folding means, which is that shown in Fig. 2, thefriction roller and the second roller 24 are both restingupon thesurface of the papers in the magazine. Rotation of the hand wheel in aclockwise direction when looking at the same from the viewpoint taken inFig. 2 will permit the spring 43 to move the carriage forwardly acrossthe magazine, thus drawing the friction roller 21 across the uppermostsheet of paper which is at this point slightly bulged by the action ofthe plate 13 on the bottom of the magazine. The tendency of the frictionroller will be to rotate in a clockwise direction upon such movement,but this tendency is prevented by the latch 23, the surface of theroller, which is preferably rubber, thus picking up or bulging theuppermost sheet of paper, forcing the same against the second roller 24into the position shown in riage would in itself raise the folded paperaway from the magazine to some extent, but as the gears 22 and 27 are inengagement, the latter gear engaging the rack 29 which is stationary,the rollers 21 and 24: are both operated uponsuch raising of thecarriage, and the paper is thus moved upwardly between the rollers intoengagement with the rollers 30 and 31. Continued rotation of the handwheel permits the rear end of the carriage to return to its initialposition, the action of the cam 45 spacing the rollers 21 and 24: assoon as the rear end of the carriage begins to descend, thus releasingthe paper and preventing the same from being hindered in its furtherupward movement between the rollers 30 and 31. The guide 28 causes thepaper to be drawn away from the roller'24 as the rear end of thecarriage descends, so that the lower edge of the folded sheet isentirely clear from the roller 24 when the latter is brought to rest inits initial position.

As the rollers 30 and 31 are being continuously operated from the shaft50 during such operation of the folding mechanism, the folded sheet isdrawn up into the pocket 33, and as the folded edge of the paper engagesthe top of the pocket, the friction roller 31 continues to draw thepaper upward, the paper thus bulging at its central portion in the spacebetween the friction roller 31 and the cooperating roller 32. These tworollers operate to thus again fold the paper and to convey the same ontothe fingers 37 of the stacking mechanism. An arm 58 is attached to thepocket and is provided for the purpose of retaining the stacked papersin such position, as will be readily understood from an inspection ofFig. .2.

The importance of having the magazine and the carriage pivoted aboutadjacent parallel axes will now be understood. As the magazine isadjusted it will be tilted more and more forwardly, and unless thecarriage be so mounted that the friction roller 21 is adapted to bemoved, upon the first movement of the carriage, in a directionsubstantially parallel with the surface of the paper, it is'impossiblefor the same to efficiently operate to pick up a single paper. T hefeatures of the invention to which particular attention is called arethe means for raising and folding a single paper and it will beunderstood. that other suitable means besides those here shown may beprovided for receiving and stacking the folded papers. While it will beseen that the folding mechanism has been so constructed and combined inthe present mechanism to efiiciently cooperate with the particular meansshown for receiving and stacking the papers, yet it will be understoodthat such last named feature of the mechanism will be controlled in itsconstruction and operation to a large extent by the use to which themachine is to be put. Thus, when handling a certain class of papers itis desirable to fold the same, once centrally and then transversely, andin such a case other means than those here shown would necessarily haveto be used. The present invention therefore resides in the mechanism forpicking up and folding the papers'and in the cooperative combinationbetween such mechanism and the means for receiving and further handlingsuch folded paper.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.
